Which condition is defined as the absence of spermatozoa in the ejaculate?

• A. Low sperm concentration
• B. Abnormal morphology
• C. Absence of spermatozoa in the ejaculate
• D. Poor motility

Answer: (C)

Azoospermia describes the absence of spermatozoa in the ejaculate. It is diagnosed when no sperm are detected in the semen on analysis, distinguishing it from oligospermia (low concentration), asthenozoospermia (poor motility), and teratozoospermia (abnormal morphology). Semen analysis assesses volume, concentration, motility, and morphology, and only this condition indicates a complete lack of sperm rather than a partial or qualitative defect. Azoospermia can result from issues with sperm production or from an obstruction in the reproductive tract, which guides further testing and management.
